摘要

The mass concentrations of coarse (PM_(10)) and fine (PM_(2.5)) particulate matter were measured in different classrooms and relevant indoors areas of Democritus University, School of Engineering, Xanthi, with portable aerosol monitoring equipment. Two sampling campaigns were conducted in different seasons. The results indicated that the average concentrations in classrooms ranged from 32-188 /μg/m~3 and 25-151 /μg/m~3 for PM_(10) and PM_(2.5), respectively. Concentration levels above 300 /μg/m~3 were usually recorded, while the PM_(2.5)/PM_(10) ratio was about 0.8. As expected, PM_(10) and PM_(2.5) average concentrations were significantly higher in the open-access meeting place of common use, indicating the significance of student trespassing and occasional smoking in the deterioration of indoors air quality.
